Disk, memory, and process management
Data storageThe database server uses physical units of storage to allocate disk space. It stores data in logical units. Unlike the logical units of storage whose size fluctuates, each of the physical units has a fixed or assigned size that is determined by the disk architecture.
TablesIn relational database systems, a table is a row of column headings together with zero or more rows of data values. The row of column headings identifies one or more columns and a data type for each column.
Damaged tablesThere are a number of ways you can damage a table.

Damaged tables

There are a number of ways you can damage a table.

The following items can damage a table:

An incorrect buffer flush
A user error
Mounting a files system or another chunk on top of a chunk
Deleting or updating when the scope of the change is not as narrow as you require

Damaged indexes can cause a table to seem damaged, even though it is not.

The oncheck commands cannot fix most damaged tables. If a page is damaged, oncheck can detect and try to fix the page, but cannot correct the data within the page.
